Hello,

Is asynchronous I/O as introduced in PG 18 also available for Windows platform and possibly for Solaris, AIX, FreeBSD platforms ?

If not maybe we should also mention in Server Configuration section that asynchronous I/O configuration is only available on Linux platforms.

Is there any other feature only available for specific platforms ? I have not found a documentation section mentioning such cases (except for installations https://www.postgresql.org/docs/18/installation-platform-notes.html).

Hi Evan, Andres,
Here is the patch (attached).
I believe this change would also be a good candidate for backpatching to previous supported versions.

Regards, Surya Poondla
